I sets of planetary gears, GQ'H/ and I are provided.

The operating illustrated, as theconstruction oi such means is Well' known.

I secure a reduced speed by locking the drumE by of its brake-barrel e.This prevents its-rotation, and the reduced speed is secured bymeans'ofthe're duction gears G, G H and HC The `gear 'Iarldfthe drumFfwhen the parts are thus arranged, are',l free yto turn upon'theirbearings.

the gear I locked, so that when the gear or pinion Gli is driven bymeans of the gear G, the tendency will be to rotate these gearsabout thegear in the opposite dithnsob'taining a reverse.'

`t'iire I haverillustrated, t

I n motor cars, particularly iorrailroad use, it is def 1 sirable thatthe gear may at tlie'salne speeds. I accomplish this result `bynieansofa reverse `mechanism, which I will nowdcscribe.

jawed clutch collar C is siidably secured te the sleeve B by anysuitable means. A pair of beveled pinions b are revolubly mounted on thedriving shaft and sleeve. T liese pinions arepro'vided with suitableljaws adapted to be engaged by the jaws of the collar.

drum F Kis `pro l means 'of these.

means for these brake bands are not here i I secure a slow reversed`speed locking thel drinn` F byincans of its brake-band e By locking thisdrum,

rection. This reyersemoveinent drives `the gear H on the sleeveB n anopposite direction; as will be evident,

fori se- 10 0 l be driven'ineither direction the gear 'so that` thewhole is' f solid construction, ,giving a high speedto By this meanseither one or the other of the gears may ie locked to the sleeve. Adriven shaft D, on which the driving sprocket D is secured7 is mountedon the l frame A. On the inner end of this shaft are beveled. gears D,arranged to mesh with the gear b. Thus arranged, by shifting the collarC-a lever C being provided for that purpose-either of the gears b may bellocked to the sleeve B, as may be desired to drive the driven shaft Din the required direction.

In motor cars for railways, particularly locomotive hand cars andinspection cars such as are used for inspecting the road-bed, etc., manyof the cars are too heavy to be lifted from the track and turned withconvenience, and it is often inconvenient to run the same.

to a turntable. It is therefore very desirable that the car may bedriven in either direction,v at its full or reduced speeds. By means ofthe reversed speed in the transmission gearing I secure another speed atwhich the car may be run in either direction.

My improved gearing is comparatively simple and economical and at thesame time is very efficient. 'lhe lparts are so arranged that the strainthereon is reduced to a minimum and consequently the structure is verydurable and 'is not likely to 'get out of repair.

While I have'illustrated and described the structure in the formpreferred by me on account ofiis structural simplicity and economy, lIam awaret'hat it is capable of considerable variation in structural'details without` departing'from my'invention.y

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
